Kyuubeey submitted a new resource:

(DATA REPLACEMENT) Toyota AE86 Improved Physics by Arch - More accurate physics for AE86 and more versions.

10.03.2019 Version 1.0

- Initial release

SHADERS PATCH IS NOT REQUIRED!

Modified, scratchmade physics for Toyota AE86 GT-APEX Sprinter Trueno. Based on suspension measurements and schematics, damper dynos and torque graphs etc.

Includes:
AE86 GT-APEX Sprinter Trueno
AE86 GT-APEX Sprinter Trueno Drift
AE86 GT-APEX Sprinter Trueno Drift Alt
AE86 GT-APEX Sprinter Trueno S1
AE86 GT-APEX Sprinter Trueno S2

Improvements and perhaps more versions are possible in the future.

Kyuubeey updated (DATA REPLACEMENT) Toyota AE86 Improved Physics by Arch with a new update entry:

Live Axle Physics update, setup change, UI change

14.03.2019 Version 1.1

- Changed driftcar default setups a bit
- Updated UI
- Attempted to improve live axle implementation: probably as good as it will get

Bashed my head at the wall for half a week on end, and still disappointed I couldn't fix the small issue in this version: only introduced very large ones. So I will release this as it is, it should still be quite good. AC axle is so extremely buggy it's unlikely it can improve for the time being.

Update in the works. I managed to actually improve the car: amazingly. There were some pure mistakes but I've also got the axle a bit more cooperative and did a bit more research on the car as a whole. :thumbsup:

Fairly happy how it's ending up, stay tuned.

Kyuubeey updated (DATA REPLACEMENT) Toyota AE86 Improved Physics by Arch with a new update entry:

Two new versions, base physics changes

12.05.2019 Version 1.2

- Added AE86 GT-APEX Sprinter Trueno Club racing version
• Racing version using mainly classic parts
- Added AE86 GT-APEX Sprinter Trueno Rally racing version
• Rally version loosely based on WRC A/6 and Finnish Corolla GT cars
• Not complete yet and needs some work but maybe it's fun for some
- Changed AE86 GT-APEX Sprinter Trueno Drift Alt
• Serious drift version with S13 front end swap
- Added "Street 80's" tires to stock car, maybe closer to tire from 1983

Oops! I left the "equal length links" in for the Rally version, but actually it is on close to stock geometry. :roflmao:

It's common for rallycars to run equal links because it's better for durability, mounts don't get torn off, but for this one I didn't do anything special yet. Maybe for 1.3. :thumbsup:

I've since also slightly worked on the mesh. Last update I posted was in May, so as you see, we're going at a staggeringly fast pace.

Update inbound in some time. Learned some things since then which make more sense + I'll implement load curves. Real exciting stuff, especially for people who like the stock car. :thumbsup:

Do you drift the drift car using 1260 degrees? or do you just use 900 degrees on your wheel.
Full 1260 degrees would be ideal, but not a lot of people have that. You can do nice relaxed drifting with 900 1:1, but for serious stuff, I suggest to scale it up for 900, so that the speed of the rack is faster, but you get the full lock @ the wheel.
